Heren, bedankt voor de hulp maar het gaat niet werken...
Toch nog een reactie gevonden:
Thank you for contacting Kensington Technical Support.
We understand that you are looking for the software for Expert Mouse Pro model # 64213. We regret to inform you that the Expert Mouse Pro model # 64213 has been discontinued and no longer manufactured by Kensington. The software which helps you to program the buttons on your trackball is not available. Hence, you can not program Expert Mouse Pro model # 64213, however the trackball can be used as two button generic mouse.
Kensington has launched a new software called TrackballWorks which is compatible with Mac OS X (with all new updates). TrackballWorks is only compatible with Expert Mouse model # 64325.
Wat mij betreft einde zoektocht, wissel nu tussen muis, pen en trackball
